Ranque-Hilsch vortex tube
For the term 'vortex-tube' used in fluid dynamics please see: vorticity
The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The air emerging from the "hot" end can reach temperatures of 200 °C, and the air emerging from the "cold end" can reach -50 °C. It has no moving parts.
Pressurized gas is injected tangentially into a swirl chamber and accelerated to a high rate of rotation. Due to the conical nozzle at the end of the tube, only the outer shell of the compressed gas is allowed to escape at that end. The remainder of the gas is forced to return in an inner vortex of reduced diameter within the outer vortex.

Building a Ranque-Hilsch vortex cooling tube
The Ranque-Hilsch vortex tube is an interesting piece of equipment. It can, without any moving parts or chemicals, separate hot and cold compressed gasses that are passed through it. Interestingly enough, you can cobble one together with very few parts for fairly cheap.

Vortex Tube - From Gyroscope.com
Vortex tubes are a type of heat pump. They have one inlet and two outlets. Compressed air is pumped into the inlet, where it is spun at high speed causing it to split into two streams, one stream giving kinetic energy to the other. The result is one outlet has hot air while the other is considerably colder.

"Numerical prediction of primary and secondary flows in a Ranque-Hilsch" by Ronan Oliver (Thesis)
The primary aim of this project is to obtain a fundamental understanding of the fluid dynamics and thermodynamics of the primary and secondary flows in a Ranque-Hilsch vortex tube (RHVT). These flows are highly complex and are three dimensional, compressible and viscous in nature. To obtain an understanding of these, a state of the art Computational Fluid Dynamics (CFD) software package is applied for flow prediction with advanced turbulence models, and is employed to predict the primary and secondary flows in a RHVT. The models that are used include : the k-e model, the SST model by Menter, and the Reynolds Stress Model. The results from the turbulence modes are analysed and compared to establish how accurate they are at computing this type of flow field. In this CFD study of the RHVT, the flow fields and temperature outputs are investigated. This study begins with the appropriate selection of experimental results from a range of authors for similar vortex tubes. These results are collated and a three dimensional model of a similar experimental RHVT is drawn, upon which an unstructured tetrahedral mesh is developed using the CAD and meshing facilities of the CFD package respectively. This model is developed in such a way that components of the RHVT could be easily adjusted in size in order to carry out small scale parametric studies of the vortex tube. The analysis moves on to the correct stipulation of suitable and accurate boundary conditions. Once a set of appropriate and realistic boundary conditions is established, the flow fields within the RHVT are captured. Initially the k –e turbulence model is utilised to perform a mesh element density convergence study with the cold static and total temperature outputs of the RHVT as the measured criteria. Once mesh independent results are established, additional turbulence models such as the SST model by Menter and the Reynolds Stress model are run on this mesh to ascertain the performance of each turbulence model. When the optimum turbulence model is ascertained and investigation was carried out into the source of heat migration in the RHVT. This began by varying the tube geometry, i.e. the cold outlet diameter, and analysing its influence on the presence of secondary flow and therefore the influence of secondary flow on the heat transfer within the RHVT. An additional analysis of the work due to friction within the vortex tube is also performed in order
